Abstract

Abstract: A novel low-molecular-mass organic gelator (DBNPM) was synthesized from 12-bromine-13, 14-dinitro dehydroabietic acid methyl ester. The title compound was characterized by ¹H NMR, ¹³C NMR, IR and MS techniques. The assembly behavior of the prepared organogelator in solution was investigated. The organogelator induced gelation in a wide variety of organic solvents. With methanol as solvent, the critical gelation concentration (C_GC) of the prepared gelator was the minimum, 0.5 g/L. But the gelatination property was the most stable in 1, 4-dioxane. Scanning eletron microscope (SEM) images indicated that the xerogels from methanol solution presented flaky structure and the xerogels from 1, 4-dioxane solution were net-like structure. Infrared spectra (FT-IR) and XRD showed that hydrogen bond was the main driving force for the formation of organogels.

Key words: methyl dehydroabietate, low-molecular-mass organic gelators, critical gel concentration, gel-sol phase inversion temperature, hydrogen bond
